To all ,wbltom t may camera Y l A Be it known that L LonisK. SGHWALL, a

' citizen of the United States, residing at Mio Chicago, in the county YofCoOk and State of Illinois, have invented la certain new vand useful Improvement lin Broilers, of which the following is a full, clear,- concise, and" exact description, referencebeing hadl toA the accompanying drawings, form-ing a part of this specification. i

This'invehtion relates to improvements in brojlers'. l

. An object'oftheinvention is to provide broiler moref particularly yadapted for usein restaurants 'and the like, which has means for relatively adjusting the grid -iron and the heat producing means, -'t'.o'gthereby insure the best results in cooking of the food.

Another object ofthe invention is to provide a broiler so'arranged that the lfood on the grid iron may be cooked fromlthe top,l by means of a gas burner, or from beneath vby means of charcoal, or other suitablefuel,

,t on a fire bed.

- the novel combinations of the parts and de- -vices as herein shown, described, or claimed.

.In the drawing forming a/part of this" "tion upon a reduced .scale of the broiler The inventionfurthermore consists in the improvements in the parts and devices, and

specification, Figure :I vis a front elevation fof a broiler showingmy improvements in connection therewitli;Fig.f2 is a side'elevaillustrated'inFig, 1; Fig. 3 is a vertical transverse section. taken substantially on the line 3--3 of Fig. 4; Fig. 4 is a vertical sectional view ait-right angles to that shown in Fig. 3, and taken on the' line 4-4 of Fig.

vse

3; Fig. 5 is a detailedfhorizontal sectional view taken on the line v5-'5 of Fig. 3.; Fig. 6 is a broken, detail sectional view similar to Fig. 3 but upon an enlarged scale; and Fig. 7 is a detailed perspective viewnof a .cam employed with my improvements.

In said' drawing, A designates the outside frame of the improved broiler, and the front wall thereof preferably comprises two portions, 11 and 12, oifset from each other, the upper portion 12y having its lower edge terminating in an outwardly and downwardly inclined flange 14. The front wall is'cut away between the iiange14, and

the upper' edge of the portion 11, to thereby provide an opening 13, through which. access may be had to the grid iron and interior of the broiler proper. i

. f l Patented Apr. M, 1913. l Appucatiaied may i, 1915. serial Nb. 25,106. l i f I As shown, the broiler is provided with a plurality 'of gas burner pipes 15, above which is disposed a horizontal asbestos, or

other heat resisting, partition 16. The partition 16 forms the bottom wall of a warm ing chamber 17, having a pivotedT-front door 18,' mounted on hinge pins 19, and adapted tobemanipulated'by a handle 20. 'An escape for` thegases of combustion from the broiler is provided by means of the outlet pipe 10. (See Fig. 4.)'

gas burners and substantially-on a horizontal plane with the lupper edge of the por. tion 1 1 of the front wall of the broiler, said 4drippihgpau 20 having -a centrally located outlet 21 through which the drippings are adapted-to fall into a drawer -22, slidably mounted in the lower `portion ofthe broiler and adapted to be withdrawn from the front thereof, as by means ofa handle 23. EX- tending varound the inner side walls'of the A dripping pan 20 is provided below the broilerat the top ofy the .drippingpan 2O l yis a ledge 24 on which is adapted to be ref movably seated "asheet 25 on whichmay be placed, a layer of sand and fire brick 26, to thereby form a bed lfor a charcoal,

or coal, or 'other suitable fuel, i'ire.

" 'Adjustably mounted between the iire bed `26 and the gas burners 15 is a horizontally `disposed grid iron 2.7, having antifriction rollers 28 secured thereto on its side edges, the rollers 28 riding back and forth upon tracks 29, formed by angle irons 30, which are vertically adjustably mounted, as hereinafter described. Secured to the sides of the grid iron 27 areU-shaped clips 31, which extend' around and under the tracks 29, and

lthusserve to guide the grid iron and keep it -in proper position, as itis pulled out and pushed fback. The angle irons 30 are secured to the upper ends of a pair of outwardly turned channel shapedl members`33,

one at each side of the broiler. The channels ics by transversely extending \cylindrical=.pipe.

3)?, with which engages a cam 38, the latter being substantially channel shaped in cross section, and fitting over the pipe 37, as appears from Figs. .3, 4 and 7. The cam 38 is secured to an oscillatable shaft 39, mounted in suitable bearings in the front and back 3, the gas burners 15, are supplied from a' is a counterbalance or weight, 45.

- As most clearly shown in Figs. -1, 2 and main pipe 47, from which'lead branch pipes 48-48, the supply of gas to each of the branch pipes 48kbeing controlled by suitable means, such as a globe valve 49. ln each of the branch pipes 48 is placed an air injector, or mixing device 50. v j On each side of the broiler is secured a sheet V51, the lower edge ofwhich is inwardly bent, as indicatedat 52 to thereby cause any drippingslto drain over into the dripping pan 20.

From the `preceding description it will be seen that the means for adjusting the grid iron 27, are simple and eiiicient; they permit of any degree of adjustment desired between the grid iron and the heat producing means; the-hand lever 4l is placed in a convenient position to thereby encourage the cook, or operator, in always properly adjusting the heat' for the material being cooked; the broiler may be adapted for cooking the food, either from thel top or from the bottom, as desired; and by mixing the gas and air and controlling the supply of gas and air to the gas burners o n the outside of the broiler, better combustionis obtained, and proper adjustment of the gas flame is encouraged, since thev adjusting valves 49 are readily accessible to the cook and are always in a cool condition, thus overcoming the objection heretofore encountered, wherein the supply of gas for the burners has been controlled by valves or cocks located within the broiler.

Although l have herein shown and described what l now consider the preferred embodiment of my invention, `yet lf. am aware that changes and modifications may` be made in the details of construction and arrangement of parts, without departing fromthe spirit of the invention,l and l contemplate all such changes and modifications asrcome within the claim appended hereto.

l claim:

ln a broiler, the combination with a suitable-frame having heat producing 'means vlocated therewithin, of a grid iron verticallyadjustably mounted within said frame, means for adjusting said grid iron, said means including depending vertical arms, a

horizontally extending brace rod connecting said arms, an operating shaft extending at right angles to said rod rand located below thesame, and a cam carried by said shaft, said cam having a grooved periphery within which slides said rod.4

ln witness that` l claim the foregoing li have hereunto subscribed my name this 81th day of April, 1915; l
